DIY Bath Bombs Without Citric Acid

Science can be full of fun reactions in the kitchen, or in this case in the bathtub! We all love relaxing in the tub, or in the case of my younger children, playing in the tub. What could be more fun than fizzing color in the bathtub that smells good too? We love making and using these bath bombs.

How to Make Bath Bombs Without Citric Acid

We spent some time last week making bath bombs without citric acid, just using what we had in the house already.

We tried out four different bath bombs recipes, all four are without citric acid because trying to find it in our small town lead to very high prices that I didn’t want to pay.

The internet was full of ideas that we took and ran with, making our own. There are four of us that made bath bombs, each of us using and making a different recipe to test and enjoy.

The first two recipes use cream of tartar, which is supposed to be a good substitute for citric acid in bath bombs, but at least in Canada, can be a little more pricey than you might want to spend, and not everyone has it in their cupboard.

    I know that we aren’t all into making things such as bath bombs, and normally I’m not, I want to be, but I tend to worry about the mess, the cost, and such. I tried, and we all had fun doing it and enjoying the end product.
